Title: Semiconductor silicon wafer and its production
Inventor: UMENO SHIGERU
IPC: H01L21/324
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a silicon single crystal wafer and its producing method by which COP(crystal originated particles) on the surface of a silicon single crystal wafer grown by a CZ method and the grown-in defects of octahedral voids as the generation source of COP at several μm depth of the surface layer are effectively eliminated. SOLUTION: The COP and voids are decreased in size by doping nitrogen, and then the crystal is heat-treated in a hydrogen and/or inert gas atmosphere to diffuse oxygen near the surface to the outside to form an unsatd. region of oxygen to remove oxide films on the inner walls of octahedral voids near the surface. Then the crystal is oxidized and heat-treated in oxygen or in a mixture gas atmosphere of oxygen and inert gas to forcedly inject silicon atoms into the crystal lattice to completely eliminate octahedral voids near the surface as well as to form an IG layer in the wafer. Thus, grown-in defects which can not be completely eliminated only by heat treatment in hydrogen and an inert gas atmosphere such as argon conventionally used can be completely eliminated from the surface to about 10 μm depth.
